Title: Lignin removal and bleaching of chemical pulp for papermaking
Inventor: KOSHIZUKA TETSUO
IPC: D21C9/10
Filed: 1994-12-12
Abstract: PURPOSE: To provide an economical means for producing highly whitened chemical pulp by removing lignin and highly whitening chemical pulp without deteriorating the pulp in the bleaching of the chemical pulp for papermaking, and further to provide a method for reducing the usage amount of a chlorine bleaching chemical to lower the environmental toxicity of the wasted bleaching water. CONSTITUTION: The method for removing the lignin from the chemical pulp for papermaking and for bleaching the chemical pulp comprises treating the steam-digested chemical pulp in high temperature and high pressure oxygen gas, adding a peroxide and a reaction catalyst comprising the oxygen acid of a group IV, V, VI element or its salt to the treated pulp, subjecting the pulp to the lignin-removing and bleaching treatments at 75-110 deg.C at a pH of <=3, and further subjecting the treated pulp to the lignin-removing and bleaching treatments in an alkaline medium.

Title: Dew condensation water discharging device for after cooler
Inventor: TAKEI MIKIO
IPC: F02B29/04
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To prevent air supply from flowing out of drainage ports and to suppress a lowering of supercharging pressure by providing a drain pipe closing the drainage ports discharging condensed dew condensation water within an after cooler cooling air supply pressurized by a supercharger according to a rise in supercharging pressure within the after cooler. SOLUTION: Because differential pressure before and behind a drain valve 15 is smaller than a prescribed value at the time of low rotation of an engine 1 in which supercharging pressure by a compressor 6 is not started to rise, a valve element 18 of the drain valve 15 is made apart from a seat part 12 with energizing force of a spring 19 and both of drainage ports 11, 17 are communicated. Therefore, dew condensation water stored within an after cooler housing 12 is discharged to the outside through both the drainage ports 11, 17, a connector 22 and a hose 23. When engine speed of engine 1 is raised, the valve element 18 is seated on the seat part 21 and communication of both the drainage ports 11, 17 is interrupted.  As a result, a part of air supply is prevented from being discharged from the inside of the after cooler 8 to the outside through both the drainage ports 11, 17 and supercharging pressure is increased.

Title: Data recording disk, and reproducing device for the data recording disk
Inventor: NISHIOKA AKIHIKO
IPC: G11B7/00
Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To make it possible to read out the information on all over a disk in a short time with the easy positioning procedure by setting the recording direction of a 1st information area to the direction from the inner periphery to the outer periphery and the recording direction of a 2nd information area to the direction from the outer periphery to the inner periphery. SOLUTION: A read-out head is mechanically positioned along the radial direction of the disk 1, then a nearest sector is read and the read-out operation is continued until the time when this sector is confirmed to be the second of the guard area by the information of sector attribute while changing the position to the inner peripheral direction with the movement of an access control part. This procedure it simplified by means of keeping to decide the sector address, whereon the positional information is recorded, for the sector address and the area at the start end of the data area.  Similarly, since the track advancing direction is made to the inner periphery from the outer periphery in the 2nd information area, the main data are arranged in order from the outermost peripheral part, then by monitoring the sector attribute during the access, the state rushed into the guard area other than the data area is instantly detected.

Title: Manufacture of semiconductor device
Inventor: KUDO NOBORU
IPC: H01L21/8238
Filed: 1989-11-27
Abstract: PURPOSE:To reduce a crystal defect by so selectively forming a reverse conductivity type diffused region to a first buried region as to surround the first region in order to separate the said conductivity type first region as a substrate from the substrate, and forming the same conductivity the second buried region as the substrate on the substrate in contact with the bottom of an isolating region. CONSTITUTION:With an oxide film 3 as a mask P-type impurity such as boron is selectively diffused in a substrate 1 to form a P-type DMOS buried P-type high concentration diffused region 41 and an element isolating P-type high concentration diffused region 42. Then, an epitaxial layer containing N-type impurity is formed on the P-type substrate 1, and then with silicon oxide 3 as a mask a P-type isolating region 7 is formed, for example, by thermally diffusing boron on an epitaxial layer 6. Here, since the region 42 is diffused in the layer 6 by auto doping, sufficient isolating characteristic is obtained. Thus, since the diffusion depth of the p-type isolating region can be reduced, warpage of a wafer, a defect of the wafer, etc., due to heat treating for long time can be reduced.
